Abstract (en)
[origin: WO2022040609A1] A system for detecting a scanning beam of x-rays includes one or more scintillator volumes oriented along an x-ray scan axis. The scintillator volume(s) receive x-rays transmitted through a target and produce scintillation photons responsively. Two or more ribbons of wavelength-shifting fibers (WSFs) are optically coupled to the scintillator volume(s) along the axis via a spatial periodic adjacency of the ribbons to the axis. The ribbons receive scintillation photons from the scintillator volume(s) via the spatial periodic adjacency as the x-ray beam scans over the scan axis. At least one respective photodetector coupled to an end of each respective ribbon detects the scintillation photons carried by the respective ribbon produces a respective signal. A signal combiner selectively combines signals from one or more ribbons, for beam positions along the scan axis, to create a combined signal representing a scan of the target. The scan can have enhanced spatial resolution.
